Likely cause: The connection is authenticated but the sync job is stuck or paused. This can happen after a plan downgrade (which may reduce sync frequency) or if the source data volume exceeds your plan’s limits. Fix:
  1. Go to Settings → Sources and click the affected source.
  2. Check the Sync History log — look for the most recent sync attempt and its status.
  3. If the last sync shows an error:
    • Note the error message (e.g., “Rate limited,” “Timeout,” or “Quota exceeded”).
    • Click Sync Now to trigger a manual sync attempt.
  4. If the last sync shows success but the “Last synced” time is old:
    • Your sync schedule may have changed. Check Settings → Subscription to confirm your plan’s sync frequency (hourly, every 6 hours, or daily).
    • Free plans sync once per day. Upgrading your plan increases sync frequency.
  5. If manual sync also fails, try disconnecting and reconnecting the source. This resets the sync cursor without losing historical data.
  6. After reconnection, monitor the Sync History for 15 minutes to confirm data starts flowing.
